Technical Reference

Sandia National Laboratory

Guidance on materials selection for hydrogen service is needed to support the deployment of hydrogen as a fuel as well as the development of codes and standards for stationary hydrogen use, hydrogen vehicles, refueling stations, and hydrogen transportation. Materials property measurement is needed on deformation, fracture and fatigue of metals in environments relevant to this hydrogen economy infrastructure. The identification of hydrogen-affected material properties such as strength, fracture resistance and fatigue resistance are high priorities to ensure the safe design of load-bearing structures.

To support the needs of the hydrogen community, Sandia National Laboratories is conducting an extensive review of reports and journal publications to gather existing materials data for inclusion in the Technical Reference for Hydrogen Compatibility of Materials. Additionally, Sandia is working internationally with collaborators to acquire newly generated data for inclusion in the Technical Reference. 


SAND2012_7321.pdf is an archival report issued by Sandia National Laboratories representing the reference information compiled as of September 2012. Individual sections of this report may be updated or added periodically at this website.

The Technical Database for Hydrogen Compatibility of Materials is intended to be a complement to the Technical Reference for Hydrogen Compatibility of Materials. Although still in the development stage, the Technical Database will provide a repository of technical data measured in hydrogen and is meant to be an engineering tool to aid the selection of materials for use in hydrogen.

The structure of the Technical Database will mirror the Technical Reference, using the same designations and classifications of materials. Below is a list of the database information compiled in the form of spreadsheets. The content is being updated continuously to eventually contain the data represented in the Technical Reference. A single material from a single study is represented in each spreadsheet: the material is indicated by the first four digits; the author and year of the primary source are represented by the following characters; and the type of data follows (i.e. tensile, fracture and/or fatigue).


On April 9th and 10th, 2013, the Hydrogen Effects on Materials Laboratory team at Sandia National Laboratories/California, invited representatives from 10 institutes in 7 different countries to participate in a meeting to identify gaps in capabilities (equipment, procedures, safety) for testing materials in hydrogen gas, particularly at high pressures (up to 100 MPa) with demanding duty cycles and long test durations. The purpose of these specialized testing systems is for applying monotonic and cyclic loading to material specimens (metals and non-metals) in hydrogen gas to measure deformation and fracture properties. The meeting provided a forum for interactive exchange of information and ideas on the participants' facility designs and operations.

The following are the presentations from each of the 10 institutes.
